------- Additional Comments from Yongjun Zhang <yongjun_zhang at apple.com>
In addition to changing PODFreeListArena to a templated class, the patch also
moves the shared interval arena from Document to RenderView, since Document
doesn't have visibility to PODInteval<int, FloatingObject*> which is defined in
RenderBlock.
